Abstract (en)
[origin: WO2010058072A1] The invention relates to a rock drilling machine and an axial bearing module. The rock drilling machine (5) is equipped with an axial bearing (18) having at least one axial piston (19, 20) for axially positioning a drill shank (7) and for damping stress pulses returning from the rock. The axial bearing comprises a module (21) that is detachable in one piece from one installation direction. The axial bearing module comprises the required pressure medium channels (27), seals (37, 37a, 37b, 37c), bearing surfaces (18), and a module frame (22, 25, 38a, 38b) having at least bearing housing in connection therewith.
